IMPROVEMENT IN PlTMEN-CONNECTIONS FOR HARVESTERS.

Specification forming part of Letters Patent No. 117,409, dated July 25, 1871; antedated July 14, 1871.

To all whom it may concern:

Be it known that I, Soni-EE J. GREEN, of the city of Syracuse, in the county of Onondaga and State of New York, have invented a new and Improved Gutter-Bar Head for Harvesters; and I do hereby declare that the following is a full, clear, and exact description of the saine, reference being had to the accompanying drawings which form a part of this specification, where- 111- Figure l represents a perspective View, and Fig. 2 a sectional View thereof.

A is the pitnian, and B the cutter-bar shaft. On the side of the pitinan-shaft I make the hollouT conical bearing or journal C. The hole h in the bearing C is made with a shoulder, S, to form a space for the operation of the spiral spring g. Upon the opposite side of the pitman-shaft A I apply the hollowT washer W, with a shoulder, o, to set in the hole h, and with the hole n through it of the saine diameter as the hollow in the bearing C, after passing` the shoulder S to the end of the bearing, so that the bolt or pin P, over which is placed the spiral spring g, will readily pass through both the bearing C and the hollow washer W. The spira] spring g is inade in the usual form, and of sufficient size to slip over the pin P and work easily in the hole h between the end of the washer WV and the shoulder S. The cutter-bar shaft has a head, D, in which is the conically-shaped hole I-i, so formed that the end of bearing G will iit into it and be a little larger than the hole at iirst.

The parts are put together by inserting the bearing O in the hole H, then insert the pin I? at the end of the bearing C, and over the end of it slip the spiral spring' g. Put on the washer IV to hold down the spring and keep the parts steady, securing the same with a key, K. I thus keep the bearing-surfaces in continued contact with each other and prevent their heating.

Vhat I claim as my invention, and desire to secure by Letters Patent, is-

The combination of the spring g with the conical bearing C, having the hollow h shouldered at S, the conical bearing D, pin I?, and washer WV, all arranged and operating substantially as and for the purpose herein specilied.
